Microsoft Access is a powerful database program that allows users to create and manage databases. It has built-in features to help construct and view information through tables, queries, forms, and reports. Access breaks down databases into a hierarchy including the database file, tables, records, fields, and data types. Users can create databases from scratch or with a wizard, then enter and manipulate data by adding, updating, and deleting records in tables or forms. Relationships between tables can also be created by matching primary and foreign keys to bring information together across multiple tables.
